It did not work for the last couple of releases.

If RUN{record_failed}+="..." is given, a non-zero execution will mark
the event as failed. Recorded failed events can be re-triggered with:
  udevadm trigger --type=failed

The failed tracking _might_ be useful for things which might not be
ready to be executed at early bootup, but a bit later when the needed
dependencies are available. In many cases though, it indicates that
something is used in a way it should not.

+Bugfixes.

+The udevadm trigger "--retry-failed" option, which is replaced since quite
+a while by "--type=failed" is removed.
 
+The failed tracking was not working at all for a few releases. The RUN
+option "ignore_error" is replaces by a "record_failed" option, and the
